Digitrax PM42 Quad Power Manager
Get the benefits of short circuit management and auto reversing without adding more boosters! PM42 Quad Power Manager lets you use a single booster and divide its output into 4 power sub-districts for automatic reversing or to improve operation by preempting booster shutdown when a short circuit is detected by the PM42. If you want to improve operation but don't need the added power (or expense) of adding a booster, the PM42 is the right answer for you. Each PM42 can run 4 sub-districts off a single booster in any combination of regular sub-districts and auto reversing sub-districts.
